Can you have an aerial sticking out.....somewhere ? Didn't think so

What if you attach the transmitter to your belt and then give
someone a great big hug (as good an excuse as any). The
signal would have to pass through 1/2 (measured at the side)
or 1 body (measured from the back)

One other alternative is to attach a thread to it and swallow

There is another way (think stuffing a turkey), but nobody wants
to be doing that on holiday
